Chuck,
This chip was made at the Burt Co in Portland Maine the same place as The Jack Todd Diamond mold ( I Think the triangle you are talking about is the diamond) mold chip was.

Mason was the distributor of this mold (Hub) the same as Jack Todd distributed the diamond mold.

Mason was head quartered in Chicago, with offices in Newark, Kansas City, and San Fransisco. Mason is still in business today but not selling chips.
HH has the records on Mason. No records I know of exist on Todd.
